illness i think

Question
she has a little bit cold fur and will not eat and has not been pooing or peeing very much...actually since her cage was cleaned a couple days ago she has not pooed that i have noticed maybe peed once or twice but thats it i have tried to force feed her mush with vitamin C but its only working a little bit..but not very well...i took her to the place where i got it and they said looked like she had a runny nose a little bit and she might have a cold but i dont think thats it.

Answer
Yes, it does sound like she has upper respiratory. Pet store pigs are often sold sick.

You need to get her to a good exotics vet and get her antibiotics. It's an emergency: http://www.guinealynx.info/emergency.html

You should continue to forcefeed (http://www.guinealynx.info/handfeeding.html ) but she won't make it if you don't get her to a vet. Not eating is very serious. She will not get better on her own. The pet store may pay for a vet if you make a big stink. They sold you a sick pig: http://www.cavyspirit.com/petstores.htm
